There is not enough information to know whether your daughter will be accepted or would have been accepted, if her race changed. What is known more analytically is the benefit to being a URM as evaluated in the lawsuit analysis. A comparison of regression coefficients for different characteristics is below, after full controls. It found that being Hispanic was very crudely similar to having the rating in any one category increasing from 3 to 2 (3 is average, 1 is best). I wouldn’t assume a highly qualified Hispanic applicant is a “lock” any more than I would assume that a highly qualified applicant who receives a 2 personal rating is a “lock.”
Being Hispanic --: +1.96
Personal rating increase from 3 to 2 – +2.08
EC rating increase from 3 to 2 – +1.41
Academic rating increase from 3 to 2 – +1.36
